[PATCH] regmap: irq: Enable irq retriggering for nested irqs

From: Grygorii Strashko
Date: Fri Feb 26 2016 - 10:53:57 EST

When nested interrupts are handled with regmap irq framework, we need to
mark the interrupts to be resend for pending interrupts on enable_irq.
Else the events might be lost for nested irqs.
